I have no oil pressure

[jiho2]

Thats like leaving the oil filter dry after a change and letting the oil pump fill it while the engine runs dry for a few seconds.

Damn, thanks for reminding me! I just put one on yesterday and forgot to put any oil in it for some reason. First time I've ever forgotten, strangely enough. Fortunately I haven't turned the key yet. I was going to drive it tomorrow. Not exactly best practice.

 

[getdowngranny]

That's why I'd like to know why you got the oil light in the first place. Somethings up, and it's hard to think of anything easily fixable that can cause such a thing.

I had the OP's exact "initial" symptoms when my engine lost oil pressure. It ended up being a dirty oil pick up screen and the front cam bearing was beggining to wear. The OP mentioned that he cleaned and removed the oil pick up tube. Was it dirty? If so, then that may have been the cause of the low oil pressure. Then he fiddled with the pump side of the system and lost track of the initial reason why the oil pressure was low opening a can of worms. SCUMBAG, how did the oil pickup screen look when you cleaned it?

 

[SCUMBAG]

The oil pick up wasn't dirty I cleaned it just because I figure why replace pump wit out cleaning pick up

 

[SCUMBAG]

Well I took the oil pump back apart and packed it with grease once again and tryed reprime it clockwise and once again nothing got valve covers off so I can watch and see if oil is getting up there and it's not did some calling around guy told me if the cover or housing have wear in it then that's the cause if it and the cover need to be replaced. After inspecting it yes it does have excessive wear could this be the problem

The more clearance the less the pump will be able to create suction on that side and pressure on the output. You can take the end plate, some wet/dry sand paper and a piece of glass. If you need a lot off to make it flat maybe some 200 grit, then move to finer and finer doing figure eights with the sandpaper on the glass to make it flat. Then you need to "set" the clearance on the gears to end cap. This needs to be tight like the main and rod clearances. You can adjust it with different thickness gaskets.

But it shouldn't matter, it should pump the same either direction. If you look at the gears they have no direction, and the drive gear turns the other gear the opposite way.

Huh? The gears may not be directional, but the inlet and outlet ports sure are!

 

[SCUMBAG]

What are the inlet and outer ports plz explain

 

[S10xGN]

Inlet port = suction screen. Outlet port = hole in block where pump discharges.

 

[SCUMBAG]

Ok so what are saying exactly what is it u saying I need to do then

 

[S10xGN]

Spin the friggin' pump CLOCKWISE! Ignore the joker that said it doesn't matter!

 

[jiho2]

Huh? The gears may not be directional, but the inlet and outlet ports sure are!

Yes, but the gears rotate perpendicular to the ports, sweeping under the ports where they enter and leave at the top of the cavity. So if the gears rotated the opposite way, each gear would still sweep under the same port to the same effect.

 

[SCUMBAG]

Ok I did that already sinned it clockwise and it didn't give me any oil pressure still a guy just told me that the oil pump gears have dots on them and they need to be lined up in order for it to build oil pressure. Now however crazy this sounded to me I'm inclined to try it cause ion have a clue as to why I do not have any oil pressure and I feel I need not take any advice into consideration but do wanna know from u guys is it any truth to this or have u eva heard of this

 

[jiho2]

Ok so what are saying exactly what is it u saying I need to do then

I'm still saying you should check the oil pressure switch. I'm not saying that's the problem and you should ignore all these other things, just that you should check the switch before banging your head too hard against the wall figuring out what it is.

 

[SCUMBAG]

So u saying check or replace the switch it's not just the light that is on I fire it up for a quick second and valve chatter

Scumbag (interesting name btw.) . . .
Sorry to hear about your troubles.
I cant add any more advice than whats already been given. Some spot on, others at best entertaining. I am subscribing for entertainment value as i do need a good laugh once in a while.

 

[jiho2]

got valve covers off so I can watch and see if oil is getting up there and it's not

What adapter did you use on the drill, and what kind of drill speed? How long did you spin it waiting for oil to appear? When I did this it took a long time and when oil finally appeared it was just a little barely oozing out. I can understand if you're getting impatient with all this BS, but it's hard to know exactly what's happening and what isn't over the Internet.

 

[jiho2]

it's not just the light that is on I fire it up for a quick second and valve chatter

Well that's what I was talking about. For a second or two that's normal. If you let it run longer than a couple of seconds and the valves still chatter, that's not normal. It takes a couple of seconds for the lifters to fill with oil, but after that the noise should disappear, and the light should go out along with the noise. So it depends what you mean by "a quick second". If you really mean just 1 second, that's normal.

 

[SCUMBAG]

Lol Jerryl yea have to tell u all bout it but we do another dist and modified it since I couldn't locate a adapter so I'm using an actual dist shafts itself and far a drill speed did it slow then fast then kinda in between tried all speeds in a manner of speaking and I spent it for bout 3 to 5 mins on each speed cause I read it could take some time didn't specific how long exactly kinda made my own judgement that it wouldn't take longer than 5 mins but I have no oil oozing so and no not impatient at all well I do when it get dark and then I'm impatiently waiting on tomorrow in high hopes of finally getting oil pressure lol and I let it run for like 5 to 10 secs to see if it will stop chattering and light to go off and it don't but I don't want to damage the motor so trying to crank it as less as possible and when I do no longer than 10 sec if that

 

[jiho2]

Ok now I'm convinced, I think ....

I've been there. What you describe sounds EXACTLY what I went through after I left a rubber plug stuck in the hole in the block (the hole the oil is supposed to get pumped into). But that's why I was hedging, because from what I know that's about what it takes.

So yeah, ignore the switch for now and which way the gears turn, and try to find out why no pressure.

 

[Jerryl]

Fair enough. This is an old video but gives an idea what you should expect as far as pressure to rpm response.
Another issue i have seen is a bad gasket between pickup tube and block preventing the prime and/or maintaining prime.

So i got to ask the obvious . . . how much oil in the pan?
